Sharpton hosts MSNBC’s “Politics Nation” on weekdays, and he has been at the forefront of recent racially-focused political rallies in Sanford, Fla., and around the country after the killing of 17-year-old black teenager Trayvon Martin.

Sharpton has been pushing these rallies despite the fact that all the evidence and information about Martin’s killing hasn’t yet come out. MSNBC has been silent on why the network is allowing Sharpton to organize these events.

Even so, Kurtz believes it’s time for MSNBC to crack down on Sharpton and hold him to the same standards to which Fox News has held its hosts.

“Folks, we criticized Hannity when he went to Tea Party rally & was yanked back by Fox,” Kurtz tweeted on Sunday afternoon. “MSNBC should hold Sharpton to same standard at rally.”

Sharpton fanned the flames of racial politics in Sanford on Thursday, and he’s expected to be a part of another rally in the central Florida town on Monday afternoon. During the rally, Sharpton admitted he was there as an activist as well, not as a media personality or news anchor. He said he didn’t believe in “drive-by activism,” and planned to see the storyline through to the end. Sharpton also raised money for Martin’s family and advocated for the arrest of neighborhood watch captain George Zimmerman, the man who shot Martin.
